Should MC be opinionated or not?

[twalmsley]

Recently we (or more accurately 'I') have added some SPARQL queries and data integrity queries to MC that try to enforce 'correct' usage, but this only really applies to Trillian - there is other work that these features don't apply to, so perhaps we should remove them?

Should MC try to enforce a particular way of structuring HQDM models or should it be totally general?

If it should be general then the efficient SPARQL queries and data integrity checks should be removed (because they are opinionated) and replaced with a general SPARQL query interface so that clients can do whatever suits their applications. This may well be the best option since MC cannot predict all the uses that HQDM may be put to, so it can't cater for them all.

Maybe there is a place for another MC module which is opinionated and can be used if needed, while core is general and not opinionated.
